Abstract

The present invention relates to a method for transmitting a sounding signal in a multiple input multiple output (MIMO) wireless mobile communication system. The method comprises: a step in which a terminal that supports a plurality of transmitting antennas receives, from a base station, at least one piece of uplink sounding transmission control information; and a step of transmitting a sounding signal using the received uplink sounding transmission control information, wherein said sounding transmission control information includes periodicity information for periodically repeating the transmission of the sounding signal, and a piece of antenna designation information for designating an antenna from among the plurality of transmitting antennas to be used in transmitting the sounding signal.
